Texas property tax protest companies typically charge between 25% and 50% of your first-year tax savings, with many charging nothing upfront and nothing if they don't reduce your tax bill. The catch is that fee percentages only tell part of the story; minimum fees, scope of service, and success rates all impact what you actually keep.
This guide breaks down the industry’s pricing models, compares costs across Texas providers, and reveals how to calculate your true net savings (savings after fees).
How Much Do Texas Property Tax Protest Companies Charge
The contingency fee model is the industry standard in Texas. Under this arrangement, you share a portion of the money the company helps you save rather than paying for their time upfront.
Industry Average: Most firms charge 35% to 50% of your first-year savings.
Ownwell: Charges a flat 25% contingency fee.
The Math: Calculating Fees From Savings
To understand the cost, you must first understand how savings are calculated. The formula is:
(Reduction in Assessed Value × Local Tax Rate) = Annual Savings
If a property tax firm helps drop your home’s value by $50,000 in a district with a 2.5% tax rate, you save $1,250.
Continuing with this example, if two companies achieve the same $50,000 assessment reduction:
Competitor with a 40% fee: You keep $750 in net savings.
Ownwell with a 25% fee: You keep $937.50 in net savings.
The Result: By choosing the lower fee for the same result, you keep ~$190 more of your own money.
Before starting a protest, it’s vital to understand the difference between market value and assessed value. This distinction determines the largest possible reduction you can achieve.

Pricing Models: Contingency vs. Hybrid vs. Flat Fees
1. The Contingency Model (Success-Based)
Most reputable firms absorb the risk of the protest. If there is no reduction, you owe nothing.
2. The Hybrid Model (The "Greater Of" Archetype)
Some firms, such as Five Stone Tax Advisers, utilize a hybrid pricing structure. For example, Five Stone often charges a percentage of savings (e.g., 40%) or a flat minimum fee (e.g., $149), whichever is greater.
This ensures the company and others like it are paid even for smaller reductions where a standard contingency fee wouldn't cover their costs, or when there is no reduction in the assessed value.
3. Flat Fee (High Risk)
Flat-fee models require payment up front. While the cost might seem lower than a percentage, you take on all the risk.
The danger of higher-fee firms often lies in the "minimum fee" or "hybrid" models. In a scenario where no reduction is achieved, a firm with a minimum fee could cost you $149 or more out of pocket, turning a "no-win" into a financial loss.
Because Ownwell has no minimum fees and no upfront costs, a "no-win" situation truly costs you $0, ensuring your protest never puts your finances at risk.

Traditional High-Volume Firm
This firm is one of the largest property tax protest firms in Texas, particularly in the Houston area. They charge a 50% contingency fee that includes all appropriate levels of protest.
Five Stone
Five Stone charges 40% of tax savings or a $149 flat fee, whichever is greater. They serve both residential and commercial properties and mostly operate in central Texas.
Regional Parcel Specialists
This company charges 40% for residential and 33.33% for commercial properties of your actual tax-dollar savings, with a $50 minimum fee per parcel. For properties with a capped market value or a special-use valuation, the fee structure may differ.
Mid-Size Texas Firm
This property tax firm uses a contingency model with fees generally ranging from 30 to 40% of savings. They often emphasize their technology platform and typically don't charge minimum fees.
North Texas Firm
This firm is exclusive to North Texas and focuses on the DFW metroplex. Their standard fee is 40% of tax savings. However, different rates apply to reductions above and below the 10% homestead cap.
The Hidden Cost of Failed Protests
The most significant risk in property tax protests isn't a high contingency fee—it's the minimum fee charged when a protest fails.
In Texas, under Section 41.43 of the property tax code, your assessed value cannot increase simply because you filed a protest. The worst-case scenario should be that your taxes stay the same.
However, if you hire a firm with a minimum or flat fee, the "worst case" actually involves losing money.
According to Ownwell’s analysis of 2025/2026 Texas protest data, homeowners paid hundreds of thousands in fees to firms even when those firms failed to reduce their tax bills.
Region* | Total Fees Owed Due to Failed Protests from Minimum Fee Firms |
|---|---|
Houston Area | $1,000,000+ |
Austin Area | $850,000+ |
DFW Area | $780,000+ |
San Antonio Area | $93,000+ |
Other Texas Counties (23 total) | $156,000+ |
*See the methodology section for defined areas
These figures highlight why it's worth confirming whether a company charges any fee when there's no reduction.
Choosing a firm like Ownwell, which has no upfront or minimum fees, ensures that a "no-win" situation leaves you $0 out of pocket.
What to Evaluate Beyond the Fee
What matters is your net savings, which is the money you actually keep after paying the company's fee. To reduce your property taxes in Texas effectively and choosing the right partner, consider:
Average Net Savings
A company's fee structure is only one piece of the puzzle; the true measure of value is the average net savings they deliver to its clients. For example:
A company with a 40% fee on an average assessment reduction of $2,000 results in $1,200 in net savings.
A company with a 25% fee might achieve a $1,800 reduction, resulting in net savings of $1,350 ($150 more).
Always focus on a provider's proven success rate and the resulting net savings after their fee is taken out.
Appeal Levels and Scope of Service
Property tax protests in Texas can go through multiple stages. Does the fee cover just the informal hearing, or does it include the Appraisal Review Board (ARB) and binding arbitration?
Some firms charge extra for arbitration or litigation. Before signing up, confirm what's included.
Technology and Evidence Quality
The strength of your protest depends on the evidence supporting it. Companies that use comparative market analysis, recent sales data, and data-driven tools often build stronger cases than those relying solely on manual research.
Better evidence typically leads to larger reductions.
Pricing Transparency
Look for companies that clearly disclose their fee structure on their website or in their initial communication. If you have to dig through fine print to understand what you'll pay, that's worth noting.

Red Flags in Property Tax Protest Pricing
Not all pricing models work in your favor. A few patterns are worth watching for.
Flat Fees With No Guaranteed Savings
Flat-fee models mean you pay regardless of whether the company reduces your taxes. While the upfront cost might seem reasonable, you're taking on all the risk. As noted earlier, some flat-fee companies also batch properties into "express settlements," which may not maximize your individual savings.
Vague Terms About Additional Costs
Some companies quote a low contingency percentage but charge separately for binding arbitration, document preparation, or administrative fees.
Ask specifically: "What costs might I owe beyond the contingency fee?"

FAQs About Property Tax Protest Costs in Texas
Do commercial property tax protest services cost more than residential ones?
Commercial fees are often structured differently due to valuation complexity. Many companies use varying contingency models for homesteaded and non-homesteaded properties.
They’ll also depend on how many properties you own or your total assets under management (AUM).
Are binding arbitration fees included in the contingency fee in Texas?
This varies by company. Some include all protest levels in their quoted fee, while others charge separately for binding arbitration or district court proceedings.
Can you negotiate the contingency fee percentage with a property tax protest company?
Some companies negotiate fees for portfolio clients or high-value properties, though standard residential rates are typically fixed.
What happens if I move after I hire a company?
Most contracts are tied to the property for the tax year. If you sell the home, you may still be responsible for the fee associated with the savings achieved during your ownership period.
What is the Texas property tax protest deadline?
The deadline to file a property tax protest in Texas is typically May 15 or 30 days after your appraisal notice is mailed, whichever is later. Hiring a company early gives them more time to build your case.
*Regions for fees paid with no property tax bill savings:

DFW Area: Dallas, Collin, Denton, Rockwall, Tarrant
Houston Area: Brazoria, Fort Bend, Galveston, Harris, Montgomery
